V REXFOBIJ 0. ANDERSON, OF HOUSTON, TEXAS DECLINOMETER BOTTLE MOUNTING Application filed October 14, 1930. seria no. 438,5 3.;

I I My-invention relates to the use of acid1bot.

tles in recording the declination of well bores from the vertical and more particularly in the means for mounting the bottle within the drilling element.

It has been found advantageous to employ an acid bottle so constructed that it may be employed as an indicator with rotating tools operating in the well bore. Thus the bottle may be mounted on, or adjacent to, the Well drill when the drill is-introduced into the hole, and the bottle may be observed when the drill is withdrawn from the Well and the lateral drift of the well bore thus noted. hen a bottle of this characteris used, it is subject to vibration and the centrifugal action due to rotation, and it is difficult to prevent splashing and movement of the corrosive liquid employed and thus obtain an ac curate reading. p p

It is an object of the invention to provide a mounting for the acid bottle whereby splashing and agitation in the liquid in the bottle may be reduced to a minimum and an accurate record thus obtained.

I also desire to provide a mounting of the acid bottle in connection'with the lubricator cage of the drill in which the bottle is readily accessible for removal with a minimum of difliculty.

In the drawing herewith I have shown a central vertical section through a. lubricator cage similar to that shown in thepatent to H. W. Fletcher, No. 1,482,787 issued Febru: ary 5, 1924 with my invention thereon.

Said cage includes a cylindrical body 1 having a deeply threaded socket 2 in the lower end whereby it may be screwed upon the upper end of the drill head. The upper end of the body is reduced materially in diameter and is threaded externally at 3 to provide attachment to the lubricator barrel, not shown. There are ducts for lubricant at l which are formed in the wall of the cage to conduct lubricant from the lubricator bar rel through the cage to connect with the bit head. Lateral openings 5 are formed in the cage to allow entrance of flushing fluid to the upper end of the drill bit. This structure is all old and well lmown and forms'no part of this invention.

I form] an upwardly extending recess or chamber 6 in the shank f the cage. Said chamber is preferably cylindrical-and of sufficient diameter to receive the acid bottle 7. The'lower end of the chamber is internally threaded to receive a closure plug 8. It will be notedthat access to the chamber may be had through the fluid openings 5 in the cage. The'acid bottle 7 is ajcup-shaped receptacle open at its upper end. It has a central post or projection 14: axially of the bottleeX- tending upwardly from the bottomto a level short of the upper end of the bottle. Said bottle is seated upona' plate or clip 9' preferably of metal which has curved arms 10 to engage about a button formed upon the upper end of'the plug 8. It will be seen that the, bottle may be mounted upon the plug when the said plug is screwed into closing position. g

I also provide a downward projection or plug llcentrally of the upper end. of the chamber 6. This may be constructed upon a pin fitted into anopening'in the shank 3 of the cage andaxially thereof and then weldingsaid pinin place as shown; The plug has an axial. recess or chamber l2having a late eral duct 13 connecting thesame with the bottle receiving chamber 6. Said plug 11 is rounded slightly on its lower end to more conveniently engage withinthe upper end of the bottle where it may act as a partial closure for the upper end of the bottle, displacing some of the liquid therein." i

When the devi'ce is assembled,-.the bottle is filled with reactant liquid up 'to alev'e l' short of the upper end of the central post/14. Upon this corrosive liquid is placed a liquid of materially lighter specific gravity not miscible' with the reactant liquid and completely filling the bottle. Kerosene or gasoline may be used if desired. When the bottle and plug are inserted into the chamber 6, the plugor stopper 11 will be received'within the upper end of the bottle and will displace partof the lighter liquid which will be forced out to fill 'thechamber 6 and compress the fair present-inthe chamber 12in the stopper.

In use, the drill in rotating tends to cause splashing and agitation of the liquid, and such tendency is opposed by the presence of the stopper 11 in the bottle and also by the air under pressure in the stopper. It is found that a clear line showing the level of the reactant liquid will be etched on the bottle which will be a clear indication of the declination of the drill and the well bore where the well is inclined materially from the Vertical. V

What I claim as new is:

1. A declinometer for use in rotary well drilling including a bottle adapted to be etched by reactant liquids, a supporting structure for use with a well drill, a chamber in said structure, a stopper plug projecting into said chamber, and a support for said bottle adapted to close said chamber with said plug projecting into said bottle.

2. A declinometer for use in rotary well drilling including a bottle adapted to be etched by reactant liquids, a supporting structure for use with a well drill, a chamber in said structure, a stopper plug projecting into said chamber, a fluid containing receptacle in said plug, and a support for said bottle adapted tov close said chamber with said plug projecting into said bottle.

8. A declinometer for use in well drilling including a bottle with reactant liquid therein, a supporting structure adapted for attachment to the well drill, a chamber therein, a screw plug to close said chamber, a support on said plug for saidbottle, and means in said chamber to displace liquid in said bottle when said bottle is placed in said chamber. a

4-. A declinometer for use in well drilling including a bottle with reactant liquid there in, a'supporting structure adapted for attachment to the well drill, a chamber there in, a screw plug to close said chamber, a support on said plug for said bottle, and means in said chamber to displace liquid in said bottle when said bottle is placed in said chamher, there being a fluid-receiving recess in said displacing means.

5. A declinometer for use with rotary drills including a supporting structure, a chamber therein, a bottle fitting in said chamber, a closure .plug for said chamber, and means to approximately close said bottle and displace liquid therein when said bottle is inserted into said chamber.

6. A declinometer for use with rotary drills including a supporting structure, a chamber therein, a bottle fitting in said chamber, a closure plug for said chamber, and means to approximately close said bottle and displace liquid therein when said bottle is inserted into said compartment, and a fluid chamber to receive fluid compressed in said chamber. 7

7 In a, declinometer for use withrotary drills, a. supporting structure, a chamber therein, a plug closing said chamber, anacid containing bottle in said chamber, means partly closing said bottle, said chamber being approximately filled about said bottle and the acid therein with liquid of lighter gravity than said acid, and a recess communicating with said chamber for gaseous fluid under pressure.

8. In a declinometer for use with rotary drills, a supporting structure, a chamber therein, a plug closing said chamber, an acid containing bottle in said chamber, means partly closing said bottle, said chamber being approximately filled about said bottle, and the acid therein with liquid of lighter gravity than said acid.

In testimony whereof, I hereunto aifiX my signature, this the 4th day of October, A. D.,
